Special Needs Paperwork

Hello all, I am after your advice as parents of SEN children. I want to set up a service to help parents with SEN paperwork - do you think there is a need for that? I have worked in SEN education (as a secondary school SENCO) for many years, and want to use my expertise somehow. I'd be really grateful for your input. I hope it's ok to use this forum to ask for your advice. Thanks.
